Active clinical trials for "HIV Infections"

The aim of this trial is to find out if immune responses to HIV can be boosted in individuals who start medicines soon after being infected. If immune responses can be boosted to the virus, this may allow the body to control HIV without the need for medications. This study is designed to test a new strategy for boosting immune responses to HIV and to evaluate if these responses allow people to have control of HIV without medicines.

For participants with HIV taking either lopinavir or fosamprenavir who have elevated triglycerides, this trial will study the change in triglycerides after switching protease inhibitors.

The purpose of this study is to see if using a combination of other drug classes, like the ones that Kaletra® and Intelence™ belong to, can still help reduce the amount of HIV in your blood. Using Kaletra® and Intelence™ without other drugs is not approved by the FDA and so their use in this study is experimental.

The purpose of this study is to determine when HIV infected children should begin taking anti-HIV medications in order to improve both patient quality of life and survival.

To investigate the potential benefit of providing passive immunity with hyperimmune anti-HIV human serum.

Examine the ability of Timunox (thymopentin) to reduce the amount and/or frequency of virus isolation. Examine the ability of thymopentin to stimulate the immune system and alter the clinical findings of patients infected with HIV who do not yet have AIDS.

To provide zalcitabine ( dideoxycytidine; ddC ) for use with zidovudine ( AZT ) in patients with advanced HIV infection. To observe serious toxicities in this population.

To demonstrate that zalcitabine (dideoxycytidine; ddC) monotherapy is safe and tolerable in the treatment of patients with AIDS or advanced AIDS related complex (ARC) who previously demonstrated intolerance to zidovudine (AZT) treatment while in Protocol N3300 (NIAID ACTG 114) or N3492 (NIAID ACTG 119). NOTE OF CAUTION FOR CONCOMITANT MEDICATIONS ON STUDY: Patients on amphotericin, pyrimethamine, sulfadiazine, trimethoprim/sulfamethoxazole, ganciclovir, intravenous pentamidine, intravenous acyclovir or oral acyclovir or other bone marrow or renal toxic drugs may not tolerate concomitant ddC. If these drugs are given concomitantly with ddC, patients should have frequent clinical and laboratory assessments, as appropriate. Drugs that are nephrotoxic or have the potential to cause peripheral neuropathy might be expected to cause increased toxicity when co-administered with ddC. Drugs that could cause serious additive toxicity when co-administered with study medication will be allowed for treatment of an acute intercurrent illness or opportunistic infection at the discretion of the investigator. Their use may be allowed with interruption of study drug for up to 35 days per episode, for a total of 90 days for the study. If the patient's condition requires chronic administration of these medications, the patient will be discontinued from study medication and followed.

To determine, in HIV-infected patients, whether switching to a new soft gelatin capsule formulation of saquinavir or to indinavir following prolonged use of the original hard capsule formulation of saquinavir results in an acute decrease in plasma HIV RNA. Resistance to anti-HIV agents occurs with increasing duration of use. In vitro studies have shown that cross-resistance occurs among protease inhibitors, although no clinical trials have been conducted to examine antiretroviral activity with sequential use of protease inhibitors or to determine whether saquinavir resistance can be overcome with higher concentrations of the drug.

PRIMARY: To identify factors associated with risk of HIV infection through heterosexual activity among urban, inner-city women. SECONDARY: To identify correlates of high-risk behaviors in order to provide a basis for future intervention studies.
